Highway Traffic Safeguard System in Harsh Environmental Areas Based on Ad Hoc

Most central and western China is untraversed and natural disasters happened frequently region with harsh geographic environment. As a result, the percentage of major and extraordinarily big accidents and casualties maintain a relatively high level. The highway safeguard system in adverse environmental areas takes the safeguard objective as `efficiently reduce casualties and property losses caused by major and extraordinarily big accidents'. The safeguard system is composted of six subsystems including personnel, vehicles, highways, environment, information and emergency rescue system. In emergency rescue system, the core of guard strategy is to ensure that the receiving of distress call and the response to social rescue are quickly. It is necessary to build a set of emergency communication network, which can organize by itself and run without reliance of established fixed base station, in order to release accident information and implement rescue. The communication network integrates hardware and software, known as MAN2TAR2. Experimental results indicate that MAN2TAR2 system has the following functions: topology change, join in network automatically, continuing transmission, multi-hop routing. Test results demonstrated that Ad hoc technology can be used in emergency rescue subsystem in harsh environmental areas and can ensure the successful social rescue mode.
